Patent JP-H04125708-A (JP)
Title: Power supply device
Inventor: MOTOYAMA HAJIME
IPC: G05F1/24
Filed: 1990-09-18
Abstract: PURPOSE:To use the output of a band-pass filter up to its maximum even in the case of the change of the constant or the amplification factor of circuit parts by controlling an input amplitude by the output of an operational amplifier dependent upon the input from a detecting circuit. CONSTITUTION:When a current flows to a load 5, a resistance R121 of a detecting circuit 6 detects the current, and a resistance R122 generates a voltage. The voltage division ratio of resistances R123 and R124 is adjusted to increase or reduce the positive input value of an operational amplifier Q13, and thereby, the output of the operational amplifier Q is reduced when the voltage generated in the resistance R122 is increased. When the output of the operational amplifier Q13 is smaller than the output of an operational amplifier Q11, a diode D14 is made conductive, and therefore, the high level output of the operational amplifier Q11 of a square wave oscillator 1 is equal to the output of the operational amplifier Q13. Thus, the waveform of the sine wave output from an operational amplifier Q12 is free from distortion.

Title: Charge transfer element and driving method therefor
Inventor: MORIMOTO MASAMICHI
IPC: H01L45/00
Filed: 1989-09-25
Abstract: PURPOSE:To record highly dense signal charges by a method wherein MIM structures are arrayed laterally with respect to an insulation substrate while a one-dimensional MIM array for laterally transferring and storing signal charge is a basic unit. CONSTITUTION:MIM structures 15 being a unit for storing signal charge are laterally arrayed on an insulating substrate 11, while a one-dimensional MIM array for sequentially storing and transferring signal charges between adjacent MIM structures is constituted. That is, a charge transfer device is realized wherein a single MIM structure 15 transfers and stores the charges in a direction of its thickness and the stored signal charges are sequentially transferred laterally. Therefore when the number of the MIM structures 15 is increased to increase the number of charge transfer and storage parts, a multilayer charge transfer and storage part can be provided without increasing the number of the layers. Thus the device can be improved in density.

Abstract: PURPOSE:To improve a picture quality by superposing and displaying plural pictures reproduced from plural data obtained by moving finely a radiation detector. CONSTITUTION:A radiation detector 14 converts a radiation transmitting data from a body to be inspected 12 to an electric projecting data, and sends it out to a data collecting part 21 side. A reconstituted picture is stored in the first memory 25M1 through a CPU19 and a memory controller 24.

Title: Surface-modified glass containing metallic ion implanted thereinto
Inventor: INUISHI NORIYUKI
IPC: C03C21/00
Filed: 1992-09-16
Abstract: PURPOSE:To regulate the light transmittance by implanting a metallic element such as Cu and/or Ag into the surface of a glass substrate and then forming a selective light transmitting layer in the surface layer part of the glass substrate. CONSTITUTION:A metallic element such as Cu and/or Ag in each or the total amount of 1X10<15> to 5X10<15>ions/cm<2> is implanted into the surface of a glass substrate with an implanting energy within the range of 30-250keV to form the objective surface-modified glass. The integrity of the ion-implanted surface layer with the glass substrate is excellent and problems of peeling do not occur. The corrosion resistance essential to the glass substrate is maintained. When the Cu ions are implanted, the resultant glass substrate provides a material for a minus filter capable of selectively absorbing and/or reflecting light at a wavelength within the range of 430-590nm (yellow, green, blue and violet light) without transmitting it. When the Ag ions are implanted, the glass substrate provides a material for a minus filter capable of selectively absorbing and/or reflecting light at a wavelength within the range of 380-490nm (blue and violet light) without transmitting it.

Abstract: PROBLEM TO BE SOLVED: To provide a low pressure stand-by part in a servo start control, stabilize an oil pressure increase and also maintain the servo start control time to a constant even by a learning and eliminate the sense of incompatibility given to a driver. SOLUTION: A servo start control has a fastfill for supplying a prescribed high pressure PS1 for stroking the piston of a hydraulic servo and a low pressure stand-by for supplying a prescribed low pressure PS2 in which the piston is kept to a stroked state. A time tST until the rotation change of an input shaft is started is detected ad the fastfill time tSA of the servo start control is corrected so that this time becomes a target time. Meantime, the servo start control time tSE is maintained to a constant by changing the low pressure stand-by time tSC in a range in which the minimum low pressure stand-by time can be ensured, even by the change of the said fastfill time tSA.

Title: Read head for magneto-optical disk
Inventor: FUKUSHIMA NOBUHIRO
IPC: G11B11/105
Filed: 1988-09-30
Abstract: PURPOSE:To accurately and easily read information by superimposing a high-frequency current upon a DC for driving a semiconductor laser and absorbing the frequency fluctuation of beat signals produced by causes other than a Kerr rotation effect. CONSTITUTION:A read head 1 for disk is constituted of a 1/4 wave plate 41, semiconductor laser 2, 1/4 wave plate 42, Farady rotator 44, output mirror 43, and photodetector 5, which are successively arranged in the described order, and nonreflecting films 21 are provided on both end faces of the laser 2. On the other hand, a magneto-optical disk 3 facing the laser 2 through the wave plate 41 constitutes an external resonator 4 of the laser 2 together with the mirror 43 provided on the opposite side and superimposes a high-frequency current of several hundreds of MHz upon the DC for driving the laser 2. Therefore, when a phase difference of + or -pi is produced, the variation of the phase different produced by causes other than a Kerr rotation effect is distributed between +pi and -pi and the variation of the phase difference produced by causes other than the Kerr rotation effect can be absorbed by the variation of phase difference produced when the high-frequency current is superimposed.

Title: Semiconductor device and its production
Inventor: MITSUMICHI KAZUHIRO
IPC: H01L21/336
Filed: 1992-09-17
Abstract: PURPOSE:To provide the active matrix substrate which flattens the intersected parts of wirings with a small number of stages, decreases the disconnection and shorting of the wirings in the intersected parts and does not generate a disturbance in orientation when the substrate is applied to a liquid crystal display device. CONSTITUTION:Semiconductor layers embedded into an insulating substrate are used partly as transistor forming regions 101 and partly as jumper lines of the intersected parts 102 of the wirings. Since the jumper lines intersected parts 102 of the wirings are embedded into the substrate 107, wirings 103, 104 passing thereon are not required to run beyond level differences and can be formed to a flat shape and, therefore, the disconnection and shorting hardly arise. The active matrix substrate for the flatter liquid crystal display device, etc., even in the final shape is thus obtd. Since the jumper lines are formed simultaneously with the semiconductor layer to be used as the active regions of the TRs, the increase in the number of stages is averted.
